Emmanuel Doit's voice of diesel reminds me of those tiny cameras following a path through the inside of the human body. I love the image of the petrol pump hose as a huge oily umbilical cord. One advantage of adopting the voice of a voiceless thing is that the emotional content is driven into the detail and left to fend for itself. This makes it possible to deal in abstractions - lines like "Instinct tells me about my duty" lodge in the mind with such vivid images to back them up.
